Patent CA-2028322-A1 (CA)
Inventor: EBBERS TIMOTHY J
IPC: G06T17/00
Filed: 1990-10-23
Abstract: Video random access memory having a random array and serial buffer is employed to speed the replication of structure state information used in the processing of hierarchical   graphic   data   structures.    Specialized circuitry in the video RAM and associated VRAM sequencer are used to perform a rapid transfer of structure state information from one row of the VRAM (the parent row) to a second VRAM row (the child row).  The VRAM sequencer is modified to perform back to back read data transfer and write data transfer operation in response to a single graphics  processor  command.   The  return  to  previous structure state can be accomplished by readdressing the VRAM row containing the previous structure state.

Abstract: Title METHOD FOR ASSEMBLING ROTORS WITHOUT FIXTURES                              Inventor Gunther T. Jensen Abstract A method of forming a clearance gap between a shrink fit rotor and a motor housing comprising the steps of heating the rotor until the rotor expands, sliding the heated rotor over a shaft having an axis, bringing the heated rotor into contact with at least one small protrusion on the surface of the motor housing, causing the protrusion to expand toward the heated rotor by transferring heat from the heated rotor to the protrusion, allowing the motor and the protrusion to cool whereby a clearance gap is formed between the rotor and the motor housing as the motor housing cools, and hermetically enclosing the rotor, the motor housing and the shaft within a compressor shell.

Title: Bandgap tuning of semiconductor quantum well structures
Inventor: EIMAN BORIS S
IPC: H01L21/20
Filed: 1990-11-29
Abstract: BANDGAP TUNING OF SEMICONDUCTOR QUANTUM WELL STRUCTURES            Abstract A method of selectively tuning the bandedge of a semiconductor  heterostructure  includes  forming  a disordered region which is spatially separated from a quantum well active region, and subsequently annealing the heterostructure so  that   vacancies/defects  in  the disordered region diffuse into the quantum well region and enhance  interdiffusion  at  the  well-barrier  hetero-junctions.  The tuning is spatially selective when the heterostructure  is masked  so that  exposed portions correspond to regions where bandgap tuning is desirable. The heterostructures of interest are  III-V material systems,  such as AlGaAs/GaAs, where the active region includes structures such as a single quantum well, a multiple quantum well, or a superlattice.

Title: Electric cooking means
Inventor: RANDOLPH GEORGE J J JR
IPC: H05B3/74
Filed: 1991-01-15
Abstract: Abstract An electric cooking device comprises at least one electric hotplate which has a non-transparent cooking surface.  A glass mounting plate which is provided under the hotplate has a partly transparent and partly non-transparent mask. An illuminating chamber illuminated by a lamp is positioned below the mounting plate with a light passage being provided in such a way that the mask gives way to a marginal area of the mounting plate surrounding the hotplate.  Light thus shines through the marginal area to the outside to indicate the operating state of the hotplate.  The mounting plate can also be made from a non-transparent material, such as sheet metal.  In such a case, the light passes through a permeable seal or other transparent mounting components.

Title: Adaptive controller in a process control system and a method therefor
Inventor: SKLAROFF MORTON
IPC: G05B13/02
Filed: 1991-10-01
Abstract: ABSTRACT OF THE INVENTION      An apparatus of a process control system for controlling a process variable of a process includes an adaptive controller tuned to the process.  The process variable output signal of the process is coupled to a difference device and also coupled to the adaptive controller, thereby permitting the adaptive controller to monitor the process variable signal independently of an error signal outputted from the difference device.  Any changes detected in the process variable signal without a corresponding change in the setpoint signal inputted to the difference device initiates an adjustment in the tuning parameters of the adaptive controller thereby providing continual, optimal, control of the process.

Title: Ridge ventilating device
Inventor: KRAMER DIETER
IPC: E04D1/30
Filed: 1990-03-30
Abstract: ABSTRACT            Ridge ventilating device.            The ridge ventilating device comprises an external, outwardly curved ridge cover element provided in the apex region with an opening and an insert located in the cavity of the ridge cover element for collecting and draining outwards any penetrating precipitation,  The insert comprises a central part arranged at a predetermined distance below the opening and lateral parts arranged in stepped manner thereto which, in the case of a certain projection over the central part, are arranged at a predeter-mined distance from one another.  From the air space air passes through the gap, is laterally deflected and guided between the lateral parts and the central part and is then, following a further deflection above the central part, made to escape outwards via the cover element opening. Conversely penetrating precipitation is led from the central part to the lateral parts, from where it is passed into the bearing region of the cover element.  A suction action is obtained in that the opening of the cover element is provided with a tear-away edge,  Alternatively to this a spoiler cap is placed over the opening and leads to a venturi effect.

Title: Picture quality correcting device
Inventor: FUNAYAMA MITUO
IPC: H04N5/911
Filed: 1992-02-07
Abstract: A picture quality correcting device which no longer relies solely on the frequency characteristic for picture quality correction, and which prevents disturbance in the group  delay  characteristic  occurring  due  to  a  large variation in the frequency characteristic of the luminance signal,   thereby  greatly  decreasing  deterioration  of picture  quality  of  the  played-back  image.   A  noise component  from the luminance  signal is  extracted by a noise canceller.   Then, the noise component is deducted from the luminance signal by inverting the polarity of the noise  component  and  composing  it  with  the  luminance signal.   The high-frequency component of  the  luminance signal released by the noise canceller is corrected by a picture-tone circuit.  The amount of noise suppression of the noise canceller and the amount of correction of the high-frequency component of the picture-tone circuit is made variable according to a control voltage by adjusting a  picture  quality  adjuster.    The  amount  of  noise suppression  of  the  noise  canceller  is  adjusted,  for example,  according to a limiting  level  setting voltage generated by an LLC circuit.
Patent CA-2060956-A1 (CA)
Inventor: MATOSSIAN JESSE N
IPC: G01B21/00
Filed: 1992-02-10
Abstract: An article (40), such as a piece of manufacturing tooling, is modified prior to use by treating a portion of its surface (38) to be worn so that the treated surface worn more than a preselected amount has a different appearance than the treated surface worn less than the preselected amount, using a treatment process in which the treated surface is at least as wear resistant as the untreated surface. Tn one approach, the surface (38) is treated by implanting ions to a preselected depth. The ions are chosen so that the substrate has a different color at depths less than the preselected depth than does the substrate at depths greater than the preselected depth. After wear, the treated surface is visually inspected for color variations that indicate wear to more than the preselected depth. The surface treatment can also be accomplished by ion implanting or ion beam mixing a previously deposited surface coating.
